Chemicals often get a bad rap, from headlines warning of "toxic chemicals" to marketing labels that boast "chemical-free or all natural" products. But what are we really afraid of? In this course, we’ll use chemophobia as a starting point to explore the fundamental principles of chemistry. Why do certain substances evoke fear, and are those fears grounded in science? Through a combination of lectures, discussions, and hands-on experiments, students will critically examine the chemical nature of  us, everyday substances, from food and water to cosmetics and cleaning agents.

Part of the Chemistry 1-4 suite, this will examine the energetics of chemical changes. Focusing on the enthalpic and entropic contributions to free energy change, we will examine how energy or work can be extracted from chemical systems and how these systems behave as they tend toward equilibrium. Types of equilibria to be covered will include acid/base, solubility, phase change, metal-ligand interactions and oxidation/reduction. The energetics of electron transfer reactions will be examined along with the practical considerations of making use of such reactions to power electric devices.
